Delhi air quality worsens to 'severe' category as smog chokes visibility

The air quality in Delhi has significantly declined, entering the 'severe' category as residents continue to grapple with heavy smog and reduced visibility. According to SAFAR (System of Air Quality and Weather Forecasting And Research), the Air Quality Index (AQI) touched 420 as of 9 am on Friday, marking the third consecutive day of severe pollution. This comes on the heels of weeks of deteriorating air quality post-Diwali, where levels were previously stuck in the 'very poor' range. Drone footage captured from areas like AIIMS and Akshardham Temple highlighted the extent of smog, making even prominent landmarks barely visible.

The Central Pollution Control Board (CPCB) recorded the AQI in Anand Vihar at a worrying 441, further solidifying the severe status of air quality across the city. Residents and morning walkers along Kartavya Path reported challenges due to the thick haze, yet life continued as usual despite the health risks.

GRAP Stage III activated; restrictions imposed to curb pollution

The Commission for Air Quality Management (CAQM) implemented Stage III of the Graded Response Action Plan (GRAP) on November 14 following an urgent review. The decision comes after the AQI remained in the 'severe' category since November 13, showing no signs of immediate improvement. Under Stage III measures, a ban on BS-III petrol and BS-IV diesel vehicles has been enforced in Delhi and NCR, alongside a halt to construction activities, except for essential government projects. 

Truck drivers and daily wage workers have voiced concerns over the restrictions, fearing significant financial setbacks, including the inability to repay vehicle loans. The CAQM has also called for public cooperation, urging citizens to use cleaner transport options, work from home, and refrain from using coal and wood for heating.

With forecasts indicating that the air quality may remain at the higher end of the 'very poor' category in the coming days, stricter measures could be implemented if pollution levels do not subside. This year’s invocation of Stage III measures came later than in 2023, reflecting a longer delay in the peak of severe pollution. The CAQM continues to monitor the situation closely and has appealed to residents to adhere to guidelines aimed at mitigating health risks during this critical period.
